I also got the walls all stacked up and square, and the formwork & reinforcing in place. I also poured the concrete into the wall cavities, but sorry no photos of this.

Next job is to make the form for the vault ceiling, and then some brick cutting to make the bevel on the opening, and also to cut the bases of the vault where they will join on to the top of the walls.

Um- the bricks are 3" not 4- same as a Pompeii, but with an extra 2" of cladding- as is recommended in the Pompeii plans. When I say extra thermal mass, I don't include the firebricks in that as it's 'extra'

You seem to be having a hard time comprehending what I'm doing. I don't know if you have a problem there or not, but it seems you just can't a grasp of what's going on.

I'm not intentionally trying to be rude or anything, and this is the last reply I'll make to you regardless of what you reply in return.

But- thanks for your input so far, but perhaps you time would be better spent helping someone else?

From your recent pics it looks like you intend to build the vault on top of the end walls. This is recommended practice for a barrel vault in kiln building. If the end walls are outside the vault when it expands with heat it puts pressure on those end walls, pushing the them out.
Although the temperatures we fire to are around half that of a kiln and the resulting expansion correspondingly less, the principle still applies for a WFO.

I just thought I'd point out that brickies oven is not a dome but a barrel oven. It would be worth it to check it out. It is his secound oven and it makes an interesting read and you can figure out his position on ovens
